The boomless rigs- mast rotation is mostly automatic, it goes where it needs to go with no input required. On these rigs supplementl mast rotation is to INCREASE rotation,(vs decrease on boomed rigs).
The only need for extra rotation is downwind sailing, & yes, it uses a forward wishbone. I had it on the 5.7, but removed it- if you use it you MUST change your order of operation, & release the rotator 1st. It is easy to forget this step if you have not bothered to use it other than deep downwind.
I found that broad reaching in a blow was plenty of excitement, & since I usually solo sail, more power was the last thing I needed!
Lighter winds/sailing deeper it can give more power.

I have both this wishbone, & the larger "rounded" one, if you decide you'd like to try it. If it's not your thing, mail it back.
That is how it was when I bought the boat. It should be rigged with a continuous line 2:1. Line dead ends on those pad eyes just inboard of the cleat-through rotator end-back throu same side cleat--around back of mast-through cleat-through end of rotator-dead end on pad eye.
I can solo right at 172lb, but only in 20mph wind. Below that I need a bag. I use a Colorado Big Bag, with a 3:1 purchase.
There was some angst recently regarding placing your line around the DS. I've washed these sails many times, you won't bend the Ds unless you drop the mast unrotated- here's why.
